Since then I've ground up the leaves this time of year and pile them up to compost them. In spring and summer I bag grass clippings and stuff those into the pile of composting leaves and it's amazing how hot those clippings get. Hot enough to roast any ticks in there for sure. So for the past few years we've had almost no ticks at all during the warm season. And I haven't had to use any pesticides.
If you find a possum in your yard, leave ‘em be and count yourself lucky.
We also have a lot of deer here and they carry ticks that get huge on them, so they're spreading them around wherever they go. We're surrounded on 3 sides by Army Corp land that's forest and filled with critters that spread them around.
I'd never seen a Golden Eagle before and it is by far the biggest bird I've ever seen. They're huge! I yelled at it and waved my arms (trying to look big) and it finally let go and flew off.
